This invention relates to windows, and has for oneof its objects `the production of a simple and elicient` window pane-supporting means for a window; and means for convenientlyholding the lower panel in an adjusted position, the window frame and window-pane-supporting means being so constructed'as lto eliminate the necessity of employing a conventional sashfor supporting the pane.

Another object of this invention is the production of a simple and-efficient means for holding the window pane in an adjusted position, and means for efliciently actuating this holding means.

Other objects and `advantages of the present invention will appearthroughout the following specification and claim.

In the drawingl Figure 1l is a front elevational view of the winn dow pane, showing the window pane and its supporting-means in position; r

Figure 21s an enlarged front elevational view of the lowerportion of the window frame and illustrating the manner of supporting the window pane of thelower panel and showing the means for holding the window pane in an adjusted position, certain parts being shown in section;

Figure 3 is an enlarged fragmentary sectional view taken on line 3-3 of Fig. 1;

Figure 4 is a vertical sectional view taken on line 4-4 of Figure 2;

Figure 5 is an enlarged sectional view taken on line 5-5 of Figure 2;

Figure 6 is a sectional view taken on line 6-6 of Figure 2.

By referring to the drawing, it will be seen that I designates the window frame which supports an upper panel preferably comprising two vertical side panes I2 and a central pane I3. The central pane |3 may be adjusted transversely of the frame I0 as indicated by the arrow A for Ventilation purposes, if desired. These panes I2 and I3 of the panel may be supported in any desired manner without departing from the spirit of the invention.

A lower panel I4 is slidably mounted upon the frame I0, as shown, and this lower panel I4 comprises preferably a glass window pane I5, the side edges of which are slidably mounted in the vertical guide channels I6 of the side rails of the frame I0. A base rail I1 supports the lower edge of the window pane I and this base rail |1 is provided with a horizontal groove I8 in its upper edge into which the lower edge of the pane I5 is securely seated as shown in Figures 2, 3 and 4. A suitable sealing packing |9 may be carried by `1 claim. (Grasa-ssi I 2 the base rail I1 forv enga-ging the outer face of the pane I5V to lprovide a weather seal, if desired. A sash lift 2|| is carried near one end of the base rail I1 as shown in Figure 2 to facilitate the lifting of the base rail |1. Aipivoted sash lift 2| is carriednear the opposite end of the base rail `|1. This pivoted sash 'lift 2| constitutes a lever-pivoted at 22, and is normally positioned atan incline to the longitudinal axis of the base rail I 1. `A latching rod 23 is pivotally secured to one end of the pivoted sash lift 2|, as at 24, and this rod 23 is tted in the socket 25 formed at one end of the base rail I1. The latching rod 23 extends longitudinallyr of the base rail |1 and normally projects Vbeyond the end of the base rail I1. "Anaperture-26 is formed transversely of the rail I1 and communicates with the socket 25 so that the Vangularl'y extending end 21 of the rod 23 may connectto `the pivoted sash lift 2|, as shown in Figures 4 and 6. `The aperture 26 is made of 'sufficient size as to permit of proper movement of the lift-2| and rod 23. A stop pin 28 extends transversely of the rail I1 and is adaptedto engage the rod 23 and prevent the rod 23 from swinging in one direction as described in the following.- I

The side rails of the frame I0 are provided with a suitable number of spaced transversely extending pockets 29 which communicate with the channels I6 and extend away from the channels IB. These pockets 29 are adapted to receive the projecting end of the rod 23 for holding the panel Il in a vertically adjusted position. A pocket 30 may be provided in the frame I0 to receive the projecting end of the rod 23 when the panel I4 is in its lowered or closed position.

When. it is desired to lift the lower panel I4, the sash liit 20 is gripped by the right hand and the upwardly extending end 2| of the pivoted sash lii't 2| is pushed downwardly by the fingers or hand of the operator thereby drawing the rod 23 out of the pocket 30 and into the channel I6. When the panel I4 has been raised to the desired heighth, the downwardly inclined end 2|b of the pivoted lift 2| is pushed downwardly thereby extending the rod 23 into one of the pockets 29 in the side rail of the frame I0. The stop pin 28 carried by the base rail |1 will act as a fulcrum for the rod 23 and the weight of the sash by resting upon the rod 23 through the medium of the pin 28 will cause the rod 23 to be retained within the selected pocket 29 and support the panel I4 in a vertically adjusted position, or the position shown in dotted lines in Figure 1. The angularly extending end 21 of the rod 23 will bind upon the lower portion of the aperture 26 and the rod 23 will in this manner be held in a set position to support the panel I4 in a desired open or raised position until an operator through the manipulation of the lever or pivoted lift 2I swings this pivoted lift 2l to a position to withdraw the rod 23 out of engagement with the selected pocket 229 when the panel I4 may be raised to a higher position or lowered to the closedposition such as shown in Figure 2. It should be understood that it is necessary to have the pockets 29 formed only in one side of the frame and it` should be understood that the rod 23 is merely a latch or supporting means and is 4not intended for a locking device. Any auxiliary locking device may be employed without departing from' the spirit of the invention.

From the foregoing description it will be seen that the present window is not provided with a sliding sash such as the conventional window sash, but that the lower sliding panel I4 comprises only the base rail I'I which supports the glass pane I5 and that thesey are the only two parts of the lower panel exclusive of t'he locking or lifting mechanism. The edgesl of the base rail Il abut against the sides of the frame I9 and the side edges of the glass pane I5V project into the channels I6 which are formed in the side rails of the frame I0. There are no weights, springs, or other mechanism employed, and because of the fact that the frame is not made up of a number of separate pieces as is the case with the conventional frame, swelling and binding will be reduced to a minimum or eliminated entirely; The device may be manufactured easily and economically and the frames could be shipped separately and the glass pane i5 is preferably of double strength, the metal parts being made of a suitable type of material which may be found of advantage. The device may be easily assembled and nailed into a building after the window frame and its component panels are assembled and may be utilized in wood as Well as plastic, tile, brick or stone buildings.

A suitable sill S is preferablyprovided as a is Number Name Date 392,924 Klein Nov. 13, 1888 429,630 Kenyonr June 10, 1890 706,845 McBride Aug. 12, 1902 1,249,176 Newman Dec. 4, 1917' 45 1,721,828 Mohun July 23, 1929 1,885,216 Axe Nov. 1, 1932 4 base abutment for supporting the frame I0 and against which the lower edge of the base rail I'I may rest.

Certain detail changes in the construction of the device may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claim.

Having described the invention, what I claim asnewis:

A sash fastener comprising a support, a sash lift pivoted on the iront surface thereof, said support having a socket formed therein and ex- `tendingrearwardly from said front surface between the pivot point of said sash lift and the 'en'dfof said support, said support having a slot formed therein and extending from the base of said socket through said end, said slot having two's'paced walls and an inner third wall, a latching member pivoted to one end of said sash lift having a rst portion extending through said socket and a second portion integral with the nrst portion and at right angles thereto and extending through said slot in a direction paral-l lel to the vfront surface of said support, and a stop pin extending across said slot between the spaced walls thereof and at a substantial distance greater than the transverse dimension of the latching member from the third wall thereof and serving with said third wall to limit the transverse movement of said second portion of the latching member. l
